UCF Physiology Exam 2 with
100% correct answers ( graded
A+)
Autonomic - answer innervates many things such as function of
internal organs in thoracic cavity, abdominal cavity, sweat glands,
wall of blood vessels (blood pressure) & has 2 parts
Sympathetic - answer When body is active. It has positive effect
on sweat glands, heart function, and respiratory system (relaxes
smooth muscle of lung) and has negative effect on GI tract [T1-
L2/3]
Parasympathetic - answer Body is at rest. Better digestion,
increases motility of GI tract, increases secretion of gastric
hormones, decreases heart rate, decrease contractivity.
Cholinergic Receptor - answer Sympathetic receptor ex.) AcH
Adrenergic Receptor - answer Parasympathetic receptor
ex.)noradrenaline
Alpha 1 - answer increases blood pressure, stimulates sweat
glands, and closes sphincter. Found in smooth muscle of blood
vessels, GI tract, sweat glands, some sphincters (urinary blood
sphincter), produce excitation (contraction, constriction)
, Propanol - answer Beta 1 blocker that decreases heart rate
Alpha 2 - answer located in presynaptic nerve terminals, platelets,
fat cells and wall of GI tract, produce inhibition (relaxation or
dilation)
Beta 1 - answer located in the SA node, AV node, and ventricular
muscles of the heart, produces excitation (increase heart rate,
increased conduction velocity, increased contractility)
Beta 2 - answer located on vascular smooth muscle of skeletal
muscle, bronchial smooth muscle, and in the walls of the GI tract
and bladder, produce relaxation (dilation of vascular smooth
muscle, dilation of bronchioles, relaxation of the bladder wall)
Nicotinic - answer located in autonomic ganglia of sympathetic or
parasympathetic nervous systems, at the neuromuscular junction,
and in the adrenal medulla; are activated by Ach or nicotine,
produce excitation
Muscarinic - answer located in the heart, smooth muscle, and
glands; are inhibitory in the heart (decreased heart rate,
decreases conduction velocity); are excitatory in smooth muscle
and glands (increased GI motility, increased secretion); are
activated by Ach and muscarine and blocked by atropine.
Albuterol - answer Beta-2 agonist acts as NE and relaxes smooth
muscle of bronchi. Used when patient is asthmatic
